Hi, does anybody know where the old deep dive presentations from http://www.ovirt.org/develop/release-management/releases/3.3/#Deep_dives are? Did we lose them in the conversion or do we still have backup somewhere? -- Martin Sivak SLA / oVirt

Multiple Data Storage Domains

--Apple-Mail=_6EA3CA6C-F1CA-43B1-A0ED-5EC9B2DD6690 Content-Transfer-Encoding: quoted-printable Content-Type: text/plain; charset=utf-8 I am having an issue in a Hosted Engine GlusterFS setup. I have 4 = hosts in a cluster, with the Engined being hosted on the Cluster. This = follows the pattern shown in the docs for a glusterized setup, except = that I have 4 hosts. I have engine, data, iso and export storage = domains all as glusterfs on a replica 3 glusterfs on the first 3 hosts. = These gluster volumes are running on an SSD Hardware Raid 6, which is = identical on all the hosts. All the hosts have a second Raid 6 Array = with Physical Hard Drives and I have created a second data storage = domain as a glusterfs across all 4 hosts as a stripe 2 replica 2 and = have added it to the Data Center. However if I use this second Storage = Domain as the boot disk for a VM, or as second disk for a VM that is = already running, the VM will become non-responsive as soon as the VM = starts using this disk. Happens during the OS install if the VM is = using this storage domain for its boot disk, or if I try copying = anything large to it when it is a second disk for a VM that has its boot = drive on the Master Data Storage Domain. =20 If I mount the gluster volume that is this second storage domain on one = of the hosts directly or any other machine on my local network, the = gluster volume works fine. It is only when it is used as a storage = domain (second data domain) on VMs in the cluster. Once the vm becomes non-responsive it cannot be stopped, removed or = destroyed without restarting the host machine that the VM is currently = running on. The 4 hosts are connected via 10gig ethernet, so should = not be a network issue. Any ideas?

Re: [ovirt-users] Storage domain for Engine does not appear

Hi, I don't understand why, but after creating a new storage pool, I have been able to attach the engine to the datacenter.

Storage domain for Engine does not appear
by Oscar Segarra 19 Nov '16

19 Nov '16

Hi, I have created a 3 node gluster (replica 3) and I have made a fresh install of the ovirt engine (4.0.5.5-1). The install process has finishes successfuly but when I connect the ovirt engine the storage domain where Engine lives does not appear. If I try to import it, I'm able to make it appear but i cannot attach it to a Data Center. Has anyone experienced this issue? Thanks a lot.

Cannot change notification settings for hosted engine in ovirt 4.0
by George Chlipala 18 Nov '16

18 Nov '16

I cannot seem to find any information on how to change the notification settings, in particular the email adresses to which to send notifications and the from address for the notifications. I have tried adding a file on the engine itself in /etc/ovirt-engine/notifier/notifier.conf.d/ and setting MAIL_FROM. I then restarted the ovirt-engine service, but notices are still using the old configuration. I even tried restarting the VM, but that did not have any effect. I have also tried editing /var/lib/ovirt-hosted-engine-ha/broker.conf however when I restart the ovirt-ha-broker service, the file is overwritten. I have found documentation about the shared configuration storage ( http://www.ovirt.org/develop/release-management/features/hosted-engine-conf…) however it is not clear to me where I would edit existing data in the shared storage. Do I just untar the files, edit, then "retar" to the shared storage? Do I need to set maintenance mode before editing? Should I shutdown the engine? After I edit the files, do I just restart the ovirt-ha-broker service or do I need to do something else? Any help in this matter would be greatly appreciated. Thanks! - George Chlipala

Re: [ovirt-users] Snapshot self-hosted engine?

Hi Martin, Keep in mind this is a single host.. so.. is there a command line operation I can run from the host to snapshot the running engine VM? Then if then update fails I can revert (by command line) the running VM from before the update. I don't mind getting my fingers dirty if I have to script it. I've used the "engine-backup" tool, but frankly IMHO a snapshot is a better way to handle an immediate update, rather than having to completely re-install the VM and restore from backup. This operation is exactly why snapshots exist. :) Thanks, -derek On Fri, November 18, 2016 3:33 am, Martin Sivak wrote: > Hi Derek, > > I do not think we support snapshots of the hosted engine VM at the > moment.

Fwd: Snapshot self-hosted engine?

Hi Derek, I do not think we support snapshots of the hosted engine VM at the moment. There would be no way to restore from snapshot anyway in case of failed upgrade (no engine would be running). Please use the standard backup/restore procedures for the engine: https://access.redhat.com/documentation/en/red-hat-virtualization/4.0/paged… Best regards -- Martin Sivak SLA / oVirt On Fri, Nov 18, 2016 at 3:58 AM, Derek Atkins <derek(a)ihtfp.com> wrote: > I'm running ovirt 4.0.4 on a single-host with (of course) self-hosted engine. > > Ovirt seems to assume in many cases that there are multiple hosts around > so you can manipulate one host while the engine is running on another, > etc. > > But in the single-host case.... how do you take a snapshot of the hosted > engine?

Snapshot self-hosted engine?
by Derek Atkins 18 Nov '16

18 Nov '16

I'm running ovirt 4.0.4 on a single-host with (of course) self-hosted engine. Ovirt seems to assume in many cases that there are multiple hosts around so you can manipulate one host while the engine is running on another, etc. But in the single-host case.... how do you take a snapshot of the hosted engine? When I click on Virtual Machines -> HostedEngine and then below click on Snapshots and then Create, I get an error: HostedEngine * Cannot create Snapshot. This VM is not managed by the engine. So... How can one snapshot the engine (e.g. prior to updating it)? -derek -- Derek Atkins 617-623-3745 derek(a)ihtfp.com www.ihtfp.com Computer and Internet Security Consultant
